I've been asked to look at kexec for ppc on 2.6.10. The syscall appears
to be present, but there seem to be additional patches for 2.6.10-mm at:
http://www.xmission.com/~ebiederm/files/kexec/
Are these patches needed?
I haven't been able to find any current official documentation, although
I found some old stuff from 2.5 and a writeup at:
http://www-128.ibm.com/developerworks/linux/library/l-kexec.html?ca=dgr-lnxw04RebootFast
Is there any official HOWTO on this? Any issues I should look at in
particular?
Thanks for any pointers,
Chris
Kexec support involves kernel level support per architecture and
a user space kexec-tools.
Generic kexec kernel support for ppc (ppc32/GameCube) was added
sometime back by Albert Herranz, and I think they got included in 2.6.10-mm1
as per:
http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.10/2.6.10-mm1/broken-out/
Albert's code was also posted on this site:
http://www.gc-linux.org/down/isobel/kexec/
ppc64 kexec kernel support was added recently (2.6.12-rc4-mm1)
Eric's site can be used for downloading the kexec-tools.
You may want to cross post kexec discussion mails to fastboot@osdl.org,
as that is the primary list where all kexec discussions happen.
Hope this helps
Thanks and Regards,
Sharada
